In July 2021, the Colorado law was changed to include requirements that the State’s Industrial sector must reduce its greenhouse gas (GHG) emissions 20% by the year 2030, compared to what it released in 2015. The Air Pollution Control Division (Division) intends to submit a proposal for rulemaking to the Air Quality Control Commission in May 2023, with the rulemaking hearing expected in September 2023. To help Division staff develop an effective rule, we are continuing to have a robust stakeholder process to gather feedback to inform the rule proposal.
